I'm pretty much a professional

Swimmer that is. A friend of mine has a gym membership to 24 hour fitness, and invited me along today. I've been wanting to get into a pool to workout. I need something that is essentially low/zero impact on my lower back, and something I enjoy: swimming. It turns out 24 hour fitness is having a little dealio for the month of February. One free guest every time you visit (for members). Hello--what a great deal. So I set off for the locker room where I was only flashed 3 times, and only got 2 whiffs of different perfume from post-workout women. I made it to the pool in one piece and spent my time mastering this one very important technique: breathing. I have this little stupid human trick that I've done since I was a kid that helps me keep water out of my nose when I go under water. The problem? I look like a fool, and it is NOT conducive to swimming laps. I'll post a picture if enough of you vote. :) So Amy taught me to inhale while stroking with the opposite arm, and exhale into the water through my nose. You guys--this is a big deal! It only took me about 5 minutes to undo a bad habit that I've had for TWENTY-SEVEN years. I was pretty pumped. I swam laps with a kick board, and then did some back strokes that I remembered from 8th grade swim class. It was a blast. This is something I could really get into. Only my hair totally reeks after just this one visit! Any advise on a swim cap? Like a good brand? Don't be surprised if you see me in the Olympics. This could be me:
Minus the fact that I'm not Japanese, I actually have a Purple swimming suit...and now that I look a little closer, I think this is a picture of a man. Google Image search has failed me. Anyway, I get the award for most improved swimmer 2008. Thank you, thank you very much.
